Quick Question: What's halfway between 1 and 9?
If you're like me, you answered "5," which is (approximately) the right answer. But if you've got a 6-year-old kid on hand, try asking him or her. According to a recent study, most little kids will answer "3," as will many people in non-literate cultures. And as it turns out, there's a solid evolutionary reason why, that guess makes sense. Watch the video to find out. (Skip to 7:30 if you can't wait!)
